title: Evolution of the prematurity before the 32nd week from 1980 to 1985 in a tertiary perinatal center in Lille, France.
abstract: 127 infants were born alive before the 32nd week of gestation in the H. Salengro obstetrical unit from the University Hospital of Lille from January 1980 to December 1985. During this period the annual number of deliveries was constant, 2700. Two periods were considered, 1980-1982 and 1983-1985. The number of such premature infants increased slightly: from 56 to 71. The most striking feature was the dramatic increase in infants born after induction of delivery for fetal reasons. Another finding is the statistically significant lowering of gestational age and birthweight of the spontaneously born infants. These trends counterweight the efficacy of the policy of prevention. When considering the morbidity and the mortality, hyaline membrane disease still plays a preeminent role in this population.
